Farting is an essential day to day activity. It helps maintain a healthy lifestyle and keeps bloating away. There are multiple types of farts, but the most common way to categorize them is by the loudness/stinkyness ratio. Essentially, the louder the fart, the less stinky (fully silent farts are the most nocive for surrounding victims). Farting can be enjoyed alone or can be turned into a group activity.
The rankness of a fart can be expressed in decibel-Farts (dBF), a logarithmic scale where dBF = 10 log10(F1/F2).
Characterizing F in standard units is a bit of a chore, but broadly speaking the resolution concentration of hydrogen sulfide (H2S) in air for humans-- the concentration at which 50% of people can detect its odor-- is about 4.73ppb, or 4.73 x 10^-9.
A cubic meter of air at sea level (1 atm or 760mmHg) at 15°C contains about 2.53 x 10^25 molecules of mixed gasses. Scaling to a cubic meter, the volume for detection of H2S for humans would be about 1.19 x 10^17 H2S molecules per cubic meter. This value is your F2, our reference intensity for detecting farts.
A typical human fart has a concentration of anywhere between .001ppm and 1ppm of H2S concentration, or between 1x10^-9 and 1x10^-6, or scaled to between 2.53x10^19 and 2.53x10^22 H2S molecules in a cubic meter of air.
Therefore the rankness of a typical fart could be expressed as a decibel ratio vs the resolution density falling somewhere between 23dBF and 53dBF.
This is a useful expression of rankness for modeling attenuation over time, accounting for dispersion, wind drift, and distance from the zero point.

How can a man fart at will? Wont he run out of gases eventually? Or swallowing air does the trick? Also now I aapire to become a professional fartist too
No discourse on farts is complete without mention of the Dutch oven. The type of cover material used to create the oven is just as important as what is eaten prior to the farting itself
